Class Dependency<T>

java.lang.Object
- com.google.inject.spi.Dependency<T>

```
public final class Dependency<T>
extends Object
```
A variable that can be resolved by an injector.
Use get(com.google.inject.Key<T>) to build a freestanding dependency, or InjectionPoint to build one that's attached to a constructor, method or field.

- Method Detail
  - get
```
public static <T> Dependency<T> get(Key<T> key)
```
    Returns a new dependency that is not attached to an injection point. The returned dependency is nullable.
  - forInjectionPoints
```
public static Set<Dependency<?>> forInjectionPoints(Set<InjectionPoint> injectionPoints)
```
    Returns the dependencies from the given injection points.
  - getKey
```
public Key<T> getKey()
```
    Returns the key to the binding that satisfies this dependency.
  - isNullable
```
public boolean isNullable()
```
    Returns true if null is a legal value for this dependency.
  - getInjectionPoint
```
public InjectionPoint getInjectionPoint()
```
    Returns the injection point to which this dependency belongs, or null if this dependency isn't attached to a particular injection point.
  - getParameterIndex
```
public int getParameterIndex()
```
    Returns the index of this dependency in the injection point's parameter list, or -1 if this dependency does not belong to a parameter list. Only method and constuctor dependencies are elements in a parameter list.
  - hashCode
```
public int hashCode()
```
  - equals
```
public boolean equals(Object o)
```
  - toString
```
public String toString()
```
